Envisaging a global village, people could transmit and receive “anytime, anywhere, and anything”. In addition, the explosive growth in internet applications such as the World Wide Web, demonstrates the tremendous increase in bandwidth and low power that the coming world of multimedia interactive applications will require from future networks. ROF technology uses multicarrier modulation like orthogonal frequency division multiplexing (OFDM), which provides an opportunity of having an increased in bandwidth together with an affordable cost and this idea has recently become a suitable topic for many research works. On the other hand, SAC-OCDMA (Spectral Amplitude Coding Optical Code Division Multiple Access) technique is able to enhance the data rate of system and increase the number of user. In this paper we introduce a ROF link using a hybrid OFDM/SAC-OCDMA technique. Keywords: Access network OFDM Radio over fiber SAC-OCDMA Copyright © 2019 Institute of Advanced Engineering and Science.

This will permit a large increase in the numbers of users and will also allow a significant increase in the available channel bandwidth, so that broadband services can be offered, in addition to the voice band services offered with current systems. The introduction of large numbers of microcells will result in the need to interconnect huge numbers of cells and microcells, and this can be carried out effectively using optical fiber, which offers a high transmission capacity at low cost [1]. Radio over fiber (RoF) systems have many advantages and applications as shown in Table 1 such as: Table 1. Advantages and applications of RoF technology Advantages Applications Indoor Outdoor - Enhanced microcellular coverage - Higher capacity - Lower cost - Lower power - Easier installation - Airport terminals - Shopping centers - Large offices, - Underground - Tunnels - Narrow streets - Highways
